M3.7 solar flare, Earth-directed CME

M3.7 solar flare, Earth-directed CME

A gorgeous filament eruption around sunspot region 3229 yesterday resulted in a M3.7 solar flare (R1-minor) that peaked at 20:30 UTC.

The event launched an asymmetrical full halo coronal mass ejection into space as seen by SOHO/LASCO. The bulk of the eruption is heading north-west and the halo outline is rather faint but it is likely that we will see an impact at Earth in the first half of 27 February. There have been no official forecasts out yet but minor G1 geomagnetic storm conditions (Kp5) seem likely, with a lesser chance of moderate G2 geomagnetic storm conditions.

Sunspot regions 3234 and 3236

Sunspot region 3229 obviously took the spot light yesterday but we have two more regions which we really should keep an eye on. Both sunspot region 3234 and 3236 have magnetic delta structures which are tell tale signs that they could produce significant solar flares. These regions are fairly quiet at the moment but both have the potential to produce M-class activity.
